Review on Uxcell A16073000Ux1254 Anti Leakage Tubeless Motorcycle by Roy Boone

Don't buy them. They look nice, but they don't hold air, which is a problem. With cores tightened, they lose their tightness, being tight and everything in between, they're still leaking. Now I have to remove the tires from the rims to replace them with more reliable valve stems.
